Put to Internal Queue

We design a scenario to post an XML content into an SAP B1 through HTTP Call. We add an "Put to Internal Queue" atom before the B1 Object's XSLT. While debugging, the XML has not been read by the "Put to Internal Queue" atom, the call result throws empty or failure. We have designed the step as the one given in B1IF help documentation, but the result turns out to be zero.
